Solution Overview
Problem
Power management for Integrated Access and Backhaul (IAB) nodes is complex due to simultaneous wireless communication and backhaul operations, which are not adequately addressed by existing technologies, leading to inefficiencies and potential performance issues.
Innovation Solution
An IAB node with plural communication circuitries generates power reports or power allocation based on configuration commands from a parent node, allowing for centralized or decentralized power management decisions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If power management is implemented for IAB nodes with multiple communication circuitries, then energy consumption is reduced and network performance is improved, but the complexity of power allocation and reporting increases
Solution Approach 1:
The patent segments power management by introducing a parent IAB node that centrally controls power allocation for multiple child IAB nodes. Each IAB node's communication circuitries are individually addressed through configuration commands, allowing granular power control without requiring complex distributed decision-making at each node.
Solution Approach 2:
The patent implements feedback mechanisms where IAB nodes report power headroom information to parent nodes, and parent nodes adjust power allocation based on these reports. This closed-loop feedback system enables efficient power management while reducing complexity through centralized coordination rather than distributed optimization.
2Productivity
If centralized power management is implemented through parent nodes, then power allocation efficiency is improved, but the signaling overhead and configuration complexity increase
Solution Approach 1:
The patent makes existing signaling mechanisms multi-functional by using configuration commands not only for standard radio resource control but also for power allocation. The same RRC signaling infrastructure is leveraged to convey both resource configuration and power management information, reducing the need for separate dedicated signaling channels.
Solution Approach 2:
The patent merges power allocation signaling with existing RRC configuration procedures. By combining power management information with standard radio resource configuration messages, the system reduces overall signaling overhead while maintaining centralized power control efficiency.
3Reliability
If power reports are generated for all communication circuitries, then complete power status information is obtained, but the reporting overhead and processing complexity increase
Solution Approach 1:
The patent applies local quality by allowing selective power reporting based on specific communication circuitries or cells that require monitoring. Instead of uniformly reporting all circuitries, the system enables targeted reporting where only relevant circuitries generate power reports, reducing overhead while maintaining accuracy for critical areas.
Solution Approach 2:
The patent implements partial action by enabling power reports for subsets of communication circuitries rather than all circuitries. The parent node can configure reporting for specific cells or circuitries based on network conditions and requirements, reducing processing complexity while maintaining sufficient power status information for effective management.

AI summary
An Integrated Access and Backhaul (IAB) node comprises a set of plural communication circuitries. Each communication circuitry of the set is configured to perform wireless communications with at one or plural other IAB nodes. The IAB node comprises processor circuitry and transmitter circuitry. The processor circuitry is configured to obtain, from a configuration command, an indication whether to generate a power report pertaining to all communication circuitries of the set or a subset of the plural communication circuitries, and to generate the power report in accordance with the indication. The transmitter circuitry is configured to transmit the power report to the parent IAB node.
